4 C09 Sound absorbing solutions Introduction Sound absorbing solutions Areas to consider when specifying Acoustics A suspended ceiling can provide two levels of acoustic performance; sound insulation, preventing the passage of sound into the room from an external source, and sound absorption, which is the control of undesirable sound within the room, in the form of reverberation. Ceiling systems incorporating products such as Gyproc SoundBloc provide the greatest level of sound insulation, while the Gyptone, Rigitone or Eurocoustic ranges provide excellent sound absorption performance for reverberation control. Aesthetics The ceiling provides a large blank canvas which can form part of the overall interior design scheme. Patterns, colours and shape can all be easily incorporated using products such as Gyptone or Rigitone. A lower key, minimalist appearance can be achieved with the clean, white finish of Gyprex or Eurocoustic systems. Air quality Historically, the role of a suspended ceiling has been limited to passive performance in terms of aesthetics, acoustics and fire resistance. With our VOC-absorbing ACTIVair technology now available as standard in all Gyptone and Rigitone products, the ceiling can now take on a more active functional role within the room. It actively improves the indoor air quality and provides the associated benefits to the occupants in the space below. Refer to C0. S0. P9 Indoor air quality. Accessibility Whatever type of ceiling is designed (table ), access to the cavity above the ceiling will inevitably be required. whether this is for inspection, maintenance or repair of HVAC and similar services. A seamless system such as can accommodate access points in the form of Profilex or Gyptone access hatches, whilst lay-in grid ceilings have the advantage of allowing access at virtually any point across the ceiling. Table Ceiling system combinations Demountable systems Gyprex tiles T T D Types of ceiling Demountable A traditional demountable ceiling consists of individual ceiling tiles which are laid into a metal grid. More recent innovations of the traditional lay-in grid ceiling include the CasoLine quick-lock-grid d concealed, and the CasoLine quick-lock-grid Corridor System. The plank system can be used to provide totally clear, unobstructed access to M&E services in commercial buildings. Lay-in ceilings are generally simple to install, easy to maintain and can be dismantled, repositioned or even reused. Seamless Systems such as or GypLyner universal ceilings provide a smooth, seamless monolithic ceiling. These types of ceiling can be used to achieve high levels of sound insulation, absorption, or both. These systems provide a large degree of flexibility and can be installed horizontally, sloped, vertically or - using CasoLine curve - giving a contoured shape. Cleanability Commercial ceilings are subject to a diverse range of cleaning regimes. A typical sports hall, for example, may require little or no cleaning during its working life. A hospital ceiling, on the other hand, needs to cope with the frequent and/or aggressive cleaning regimes required in clinical areas. Ceiling systems such as Gyprex bio provide a wipeable vinyl surface with an integral biocide, preventing the growth of fungi and bacteria, including MRSA, E. coli O7 and Salmonella. Additional Information Our Gyptone range offers the highest level of accessibility to the ceiling cavity. Gyptone Hatch, Gyptone Plank and the Gyptone TRAP system are ideally suited to where regular or unrestricted access to the cavity is required and can be used either as a stand-alone solution or in conjunction with another Gyptone ceiling.

12 C09 Sound absorbing solutions design Building design comprises Gypframe MF7 Primary Support Channels and Gypframe MF Ceiling Sections which forms a suspended frame to which Gyproc, Gyptone, Rigitone and Glasroc boards can be fixed. Planning key factors The depth of the ceiling cavity is a minimum 00mm. Relative humidity ceilings lined with Gyproc, Gyptone, Rigitone or Glasroc specialist boards are suitable for use under normal occupancy conditions. Buildings in which they are used should be dry, glazed and enclosed, with environmental conditions of no greater than 70% RH at 0 C to 0 C. For high humidity / high moisture conditions use Gyproc plasterboard mr variants or Glasroc F multiboard. Refer to C0. S0. P0 Robustness. Acoustic performance Gyptone and Rigitone boards are perforated and designed to provide sound absorption when used in conjunction with an airspace behind the ceiling. Increased levels of sound absorption can be achieved by including insulation over the back of the ceiling. Where sound insulation room-to-room is required, sound attenuation D n,c,w of 9dB can be achieved by the inclusion of 00mm Isover Spacesaver Ready-Cut over the back of the ceiling. Alternatively, other design considerations should be adopted such as extending adjoining partitions into the plenum void or installing a plenum barrier. Refer to C09. S0. P0 Sound absorbing solutions introduction, tables and. Thermal performance Isover insulation can be laid over the suspension grid to provide the required standard of thermal insulation. Contact the British Gypsum Technical Advice Centre for further guidance. Ceiling lift Changes to Building Regulations Approved Document L, airtightness requirements within dwellings, can lead to greater changes in air pressure when a door is opened. The ceiling is normally the lightest fixed element in the room, and therefore most likely to be affected by this change in pressure. This can cause the ceiling to lift, which may create a noise. Whilst this noise can be annoying to the occupier, it has no detrimental effect on the performance of the ceiling. The designer should consider incorporating a pressure release system to minimise the risk of ceiling lift. Where sufficient pressure relief cannot be designed in, it is recommended that the Gypframe MF Ceiling Section and the Gypframe MF7 Primary Support Channel should be screw-fixed together using two British Gypsum Wafer Head Jack-Point Screws at each intersection, particularly where non-perforated board linings are specified. Imposed loads Tables and provide loading data for the suspension grid for Gyproc, Glasroc specialist, Gyptone and Rigitone boards respectively. Maximum loads will be reduced by % when Gypframe FEA Steel Angle is fixed directly to the soffit (modified loads are shown in brackets).

Gypframe MF7 Primary Support Channel. Suspension Gyproc, Glasroc specialist and Gyptone board linings Fixing points for suspending the metal grid are required at 00mm centres in each direction. Suitable fixing devices should be employed when fixing to the structure. The ceiling grid can be suspended from a concrete soffit using Gypframe MF Soffit Cleats and Gypframe MF8 Strap Hanger, or alternatively, Gypframe FEA Steel Angle. The latter provides a more robust suspension support, which restricts any flexing of the lining when pressure is applied from below. Gypframe FEA Steel Angle is therefore the preferred suspension option when a plaster finish is specified to Gyproc boards. If Gypframe FEA Steel Angle is used, it is recommended that it is fixed to the soffit via Gypframe MF Soffit Cleats. For single board solutions only, Gypframe FEA Steel Angle can be used to fix direct to the soffit. The angle should be cut along the spine with both flanges bent over. However, this will reduce the maximum loads that the grid is capable of supporting by %. Fixing Gypframe FEA Steel Angles direct is also not suitable if the ceiling is likely to deflect due to varying pressures and is not suitable for fixing to a sloping substrate. C09. S0. P0 british-gypsum.com

13 design (continued) Suspension Rigitone board linings Gypframe MF7 Primary Support Channels are fixed at 000mm centres. Fixing points to the structure for the Gypframe MF7 Primary Support Channels are required at 900mm centres. In addition to this, the Gypframe MF Ceiling Section should be installed at nominal 0mm centres. Refer to British Gypsum Ceilings Installation Guide for full details. Partition to suspended ceiling junction Where a GypWall metal stud partition is fixed to the framework of a ceiling, in accordance with British Gypsum s installation instructions, its permissible maximum height is equal to that of where it is fixed direct to a structural soffit of the same height. In situations where a GypWall metal stud partition passes through a ceiling, which is to both sides of the partition and appropriately fixed to both this partition and perimeter partitions / walls, consideration can be given to the lateral restraint provided by the ceiling when developing the partition specification. The relevant maximum height is the greater of the floor to ceiling or ceiling to structural soffit height. Care should be taken during installation of tall partitions so as to not adversely affect their performance. Contact the British Gypsum Technical Advice Centre for further guidance. Services The plenum can be used to route all service requirements including ducting, pipework, electrical cables and conduit. Where light fittings, access panels and similar components are incorporated as part of the design requirements, consideration must be given to maintaining the integrity of the ceiling to meet fire resistance and sound insulation requirements. Refer to tables or for maximum recommended loads. Fixtures Fixings to the system should always be made into the metal grid or to supplementary framing. Some adjustment of the primary grid may be required to support heavier fixtures, refer to tables and. Where loads outside this range are anticipated, independent suspension should be provided from the structure. Control joints Gyproc Control Joints may be required in the ceiling to relieve stresses induced by expansion and contraction of the structure. It is recommended that they coincide with movement joints within the surrounding structure. Rigitone expansion joints Rigitone boards should be cut 0mm short of the perimeter wall and should not be fixed to the perimeter channel. Refer to construction details 9-0. Board finishing Refer to C08. S0. P0 Jointing. Additional care and attention should be exercised when jointing Gyptone and Rigitone boards so as not to fill the perforations and impair the acoustic performance of the finished ceiling.
